**Public sector unions** influence policy decisions by advocating for the interests and rights of workers within government employment. These unions engage in collective bargaining, negotiating wages, benefits, and working conditions on behalf of their members. Their organized efforts can impact a range of policy areas, including labor rights, public services, and education. By mobilizing members, conducting campaigns, and forming coalitions, public sector unions can sway public opinion and political agendas. Their engagement in political advocacy ensures that the voices of public employees are considered in policy discussions, ultimately influencing legislation related to their rights and welfare.
